Mate'nt N0. 653fl89; dated July 10, 1900.

- Application filed February It), 1900 Serial No. 4,836. Remodel) To all whom it may concern.-

Be it known that I, JOSEPH E. DYRNES, of Newark in the county of Wayne and State of New York, have invented a new and useful Improvement in Antirust Vessels, which improvement is fully set forth in the following specification and'shown in the accompanying drawings.

My invention relates to sheet-metal ware genera'lly but more particularly to the class antirust tinware, the device be-' in g for thepurpose of preventing the rusting of thelower parts of the vessel. The object of my invention is to provide an antirust vessel so constructed that liquid 'cannot enter between the antirust sheet and the bottom of the vessel whetherplaeed within 1 the vessel or surrounding thesamc, solder not being depended upon to make the joint tight againsttheinflow of therliguid. let-'- -feet this by making the antirust sheet large in diameter and extending its edge beyond the outside of the pail and folding the same into theseam at the bottom. I The invention is hereinafter fully described, and more particularly pointed out in the 7 claims.

Referring to the drawings, Figures 1 to 4, inclusive, are longitudinal, diametrical sections of parts at the bottom of a tin vessel,

showing diiferent'stages in the process of completing-the same, the metal sheets being exaggerated in thickness for the purpose of clearness. Fig. 5, drawn to a small scale, shows a complete vessel. I

A is a metal sheet, as tin, forming the sides of the vessel, B .being the bottom sheet or plate, and O the superimposed sheet of antirust material. The form of the pail or Yes sol is immaterial to this invention, likewise the form or configuration of the sheets B and G as to their middle parts at D. Thesesheets may be either flat or crowning, touching each other throughout their adjacent surfaces or separated with space between, orotherwise curved or bent, as may be desired. The body of. the vesselisformed with an outwardly-turned flange a, Fig. 1, and the sheets B O are formed with flanges e and'f, adjacent to and coacting with the flange a.

The sheets B C are made contiguous adjaof the side A of the vessel, as shown. 'eorrstructed the outer part or flange c of the cent to the inner surface of the vessel, as

shown at b 0, being bent thereatto form a circular downwardly-projecting foot (Z, Figs. 4 and 5, and finally bent outward to form the abovesmcu-tioued flan gcs e f, parallelwith the flange a The proportion of the parts is such that the flange e extends beyond the flange a and the flange f extends beyond the edge of the flange e.

In constructing the vessel the outer edge -0the flange f is first turned up against the periphery of the flange e, as shown in Fig. 2.

The two flanges e fare then together turned over the outer edge of the flange a, asshown in Fig. 3, the final operation in forming the head or band g being to turn at once all three flanges'to vertical positions, as shown-in Fig.

'4, bringing the surface h of the flange f, Fig.

3, to press snugly against the outer surface Thus autirust sheet 0 is wholly inclosed within the folds of the sheet B, forming the bottom of the vessel, and between said sheet and the flange a of the vessel. This construction renders the joint or seam atthe bottom of the "pail tight and prevents the inflow of liquid between the plates or sheets B and O.

- In constructing the vessel solder is not employed on-the outside in forming the-band g,

but is usually applied on the inside at i'to strengthen the structure.

What -I claim as my invention is- I 1. A sheet-metal vessel having a bottom plate and an antirust sheet or plate supci imposed thereon, the body of thevessel being formed with an outwardly-projecting flange and said bottom plate and antirust sheet having outwardly projeeting flanges adjacent to and coacting with said flange oi the body, the flanges of the two bottom plates or sheets extending beyond the flange of the body of the vessel, the one bent over the other and both embracing the flange of the body substantially as and for the purpose specified. J

2. A sheet-metal vessel having a. bottom plate, and a superimposed antirust sheet or plate, the body of the vessel and said antirust sheet and the bottom plate each having an outwardly-turned flange, the flange'of the antirust sheet extending beyond the flange of the body of the vessel, and the flange of the the an'tirnst sheet, the flanges of the antirust tom plates being fe'rmed withontwardlyfpr "npofl'the other, one being of antirnst mate- I bottom plate extending beyond the flange of jectiug parts or flanges, said three flanges being of different lengths and bent one over the other and folded or rolled into an external bead or band for the vessel, substantially as shown and described.

In Witness whereof I have hereunto set my hand, this 19th day' of January, 1900, in the presence of two subscribing witnesses.
